clamps are called "C" clamps because of their C shaped frame‚ but are otherwise often called G-clamps or G-cramps because including the screw part they are shaped like an uppercase letter G. Description C-clamps or G-clamps are typically made of steel or cast iron‚ though smaller clamps may be made of pot metal. At the top of the "C" is usually a small flat edge. At the bottom is a threaded hole through which a large threaded screw protrudes. One end of this screw contains a flat edge of similar

Domestic high manganese steel has been gradually replaced by alloy steel liner plate. With the application of alloy steel liner plate‚ it has become the market mainstream. Ball mill liner plate is used to protect the cylinder body. Many customers complain that liner plate’s life span is too short and the production cost is too high. With advanced technology in producing liner plate‚ KAIYUAN COMPANY can offer first-class quality and reasonable price to customers. Both casting steel ball and liner plate are

The present work investigates the mechanical properties and tribological behavior of Al-B4C composites. Attempts were made to overcome the wetting problem between B4C and liquid aluminium at lower temperatures for promising the mechanical and tribological behaviour of the Al -B4C composites. AA6061-B4C particle reinforced composites were produced through casting route at 850ºC with K2TiF6 added as flux to overcome the wetting problem between B4C and liquid aluminium metal. The Aluminium B4C composite
